- On Android 8.0 (Oreo), since this app uses PIP (Picture In Picture) function, if user presses the Home key during playing a video by this app, screen size of this app becomes small and user can operate other applications behind this app. This is the latest feature on Android. Please try it.
- On Android 8.0 (Oreo), we delete Alarm function.
